## Overview of the AD8063ART-R2 The **AD8063ART-R2** is a high-performance, rail-to-rail output voltage feedback amplifier manufactured by **Analog Devices**. It belongs to the **FastFET™** family, which utilizes a proprietary junction field-effect transistor (JFET) input stage to achieve high speed and extremely low input bias current. The "ART" suffix typically denotes the package type (SOT-23), and "R2" refers to the specific tape and reel packaging quantity. --- ### 1. Key Technical Specifications | Parameter | Value / Specification | | :--- | :--- | | **Input Type** | FET Input (High Impedance) | | **Output Type** | Rail-to-Rail | | **Bandwidth (-3 dB)** | 320 MHz | | **Slew Rate** | 650 V/µs | | **Input Bias Current** | 1.0 pA (Typical) | | **Supply Voltage Range** | 2.7 V to 8.0 V (Single) or ±1.35 V to ±4 V (Dual) | | **Supply Current** | 6.8 mA per amplifier | | **Package Type** | 6-lead SOT-23 | --- ### 2. Functional Features * **High Speed:** With a 320 MHz bandwidth and 650 V/µs slew rate, it is ideal for pulse processing and high-speed data acquisition. * **Low Noise:** It offers a low input voltage noise of **7 nV/√Hz** at 100 kHz. * **Disable Feature:** The AD8063 variant includes a power-down/disable pin, allowing for power savings when the amplifier is not in use. * **Settling Time:** It features an exceptionally fast settling time (9 ns to 0.1%), which is critical for driving Analog-to-Digital Converters (ADCs). --- ### 3. Pin Configuration (SOT-23-6) | Pin No. | Name | Description | | :--- | :--- | :--- | | 1 | Vout | Amplifier Output | | 2 | V- | Negative Supply | | 3 | +In | Non-inverting Input | | 4 | -In | Inverting Input | | 5 | Disable | Power-down Control (Logic High = Off) | | 6 | V+ | Positive Supply | --- ### 4. Common Applications 1. **Photodiode Pre-amps:** Because of the pico-ampere input bias current, it is perfect for converting light-to-voltage without adding significant error. 2. **ADC Drivers:** Its high speed and fast settling make it an excellent buffer for high-speed ADCs. 3. **Active Filters:** Used in high-frequency filter designs where precision and speed are required. 4. **Professional Cameras:** Used in CCD or CMOS imaging processing chains. --- ### 5. Implementation Example Below is a simple representation of how to configure the AD8063 as a non-inverting buffer: ```python # Conceptual Pin Connection for a Unity Gain Buffer # Pin 3 (+In) -> Signal Source # Pin 4 (-In) -> Connected directly to Pin 1 (Vout) # Pin 6 (V+) -> +5V (with 0.1uF bypass capacitor) # Pin 2 (V-) -> Ground (0V) # Pin 5 (Dis) -> Ground (to keep the chip enabled) ```
